Ruairi started singing as a chorister at St Davids and St Paul’s Cathedrals, later taking up a choral scholarship at King’s College, Cambridge.
Much in demand as an interpreter of Baroque repertoire in the UK and abroad, he recently made his debut at the Wigmore Hall and Leipzig Bachfest, performing Bach's Johannes-Passion 1725 with Solomon's Knot. Other engagements have included Johannes-Passion (arias) with both Adelaide & Tasmania Symphony Orchestras with Stephen Layton, as well as the annual Good Friday performance with Polyphony/Orchestra of the Age of Enlightenment at St John's Smith Square. In 2018 he took part in a Bach Cantata Ring with Sir John Eliot Gardiner and the English Baroque Soloists, performing BWV61, 78 & 110 at The Royal Concertgebouw, Amsterdam, the Wiener Musikverein, the Barbican Centre and the Chapelle Royale, Versailles. Future engagements include Bach’s Matthäus-Passion with Ben Nicholas/Florilegium at both St John’s Smith Square/Passiontide at Merton, and Bach’s Messe in h-Moll with Stephen Layton and the Slovenian Philharmonic Orchestra.
Equally at home with larger-scale symphonic works, he sang in the world premiere & recording of Stanford's Mass Via Victrix with the BBC National Orchestra & Chorus of Wales and Adrian Partington. Other engagements have included Mendelssohn's Elijah in Worcester Cathedral, Beethoven's Missa Solemnis with Ben Palmer/Covent Garden Sinfonia and Vaughan Williams’ A Cotswold Romance with the Lebanese Philharmonic Orchestra, and he will sing Verdi’s Messa da Requiem and Howells' Hymnus Paradisi for the first time this Spring. On the operatic stage, he debuted Prologue/Quint in Britten’s Turn of the Screw at Barnes Music Festival and took on multiple roles in Purcell's The Indian Queen with Le Concert d’Astrée and Emanuelle Haïm at l'Opera de Lille in the autumn.
Ruairi volunteers for the UK Refugee Council as a cricket coach and is a keen photographer and artist. He continues his studies with Paul Farrington and Caroline Dowdle.
